    Basic electrical question involving an electric fencer.

    Well in fact it is current that causes the shock so insulating shoes would prevent shock.......same problem occurs when an animal is standing on very dry ground.......with a single hot wire fence construction...or if the fencer is inadequately grounded Back to the original question......seems...

    Should intercooler be painted/anodized for max heat transfer?

    Well in another application flat black paint always enhanced overall cooling over even tarnished copper, aluminum, & steel surfaces. I have done lots of heat rise test...don't know if I really understand all the theoretical whys but.. Radiation cooling is usually more significant than people...

    Power factor correcting

    1). Assume single phase for illustration. Then 800amps at 480volts is equal to 384 kva (800*480/1000). 2). If power factor is 0.8 this means cos=0.8 and then the sine = 0.6. KVAR=KVA times sine = 384*0.6 = 230.4kvar. 3). So the circuit is has 230.4 kvar of inductive reactance, so if you...

    Gear ratio vs powerband

    Before I put 4.10 gears in my 1996 LT4 Corvette I plotted rear wheel torque vs mph for both the stock 3.45 and 4.10 gears based on actual dyno curve. In essence the big gain in rear wheel torque occurs only in first gear up to the shift point(mph) with the 4.10 gears. After this mph it flops...

    ATF in manual gearbox?

    idano Perhaps I am being too stubborn, but I understand what they are saying, I just don't understand why. What is there about a ZF6 that it requires such a "unique" lubricant?? Further on what basis would I choose between Castrol vs the GM fill? Viscosity?? Royalpurple claims to...

    ATF in manual gearbox?

    Actually ZFDOC gives both lubicants as alternatives & I am pretty sure GM still stands by its original recommendation. http://www.zfdoc.com/techinfo.htm Still do not understand which is best or why other lubricants are not acceptable. Is bronze unique to the ZF6?? no_stray_voltage@yahoo.com

    ATF in manual gearbox?

    I am familiar with www.zfdoc.com What is there that is so different about the ZF6 that it requires such a special lubricant??? The Castrol product is only available at BMW dealers at about $9 per quart. My Corvette at just a little over 30K miles still has the factory fill. Just trying to get...

    ATF in manual gearbox?

    Tmoose Thanks for your reply regarding ZF6 lubricant.....The question still remains as to alternate lubricants...for example what about MobilOne in 5W30 vs the GM5W30 special lub or what about Mobil1 in 15W50 vs the Castrol 10W60 Seems to be issues regarding viscosity, change intervals, and...

    ATF in manual gearbox?

    idano or others Can you provide any insight into the correct/acceptable lubricant for the ZF6 transmission as used in 1996 Corvette? GM speicifies a special 5W30 lubricant, which no one else has available as equivelent. ZF now says to use Castrol TWS 10W60. What gives...

    stray voltage(earthing in dairysheds)

    Just wondering if you have solved your problem or if you are still looking for additional information???? no_stray_voltage@yahoo.com

    Partial discharge / corona discharge

    I think this link to ASTM supports my view of the interchangeability of the two terms. http://www.astm.org/cgi-bin/SoftCart.exe/DATABASE.CART/REDLINE_PAGES/D1868.htm?E+mystore no_stray_voltage@yahoo.com

    Stray Voltage question

    Please review the above posts, I never "ask how do the cows complain about stray voltage" I don't won't this thread to become a series of personal attacks. I agree Ohio Edison has many good people. Wisconsin already has significant legislation regarding stray voltage. Repeating one...

    Stray Voltage question

    to jbartos Oh my, we MUST be analytical with equations to be engineers??? Well I don't disagree that often we need to quantify what we are doing, but sometimes we just need to know what we are doing.... For example: The very first farm I investigated indeed had measurable stray voltage, cow...

    Stray Voltage question

    twosockets & jbartos I am not sure I understand your comments, BUT Stray voltage on diary farms is in fact a legitimate engineering concern. Unfortunately there a many "quacks" trying to make a quick $ from the often emotional responses to this phenomona. What is really unfortunate...

    Partial discharge / corona discharge

    DougMSOE Sorry to disagree, but in reality the term "corona" is also often used to describe partial discharges that occur in voids of solid dielectrics. Likewise the term partial discharge also discribes the ionization around a conductor in air where a complete breakdown of the gap...
